Has anyone ever heard of these systems or have any experience with them. Looks interesting and at this price point maybe worth a try.

Can our fuel lines and systems take E85 without rotting out?

Not sure. I read lots of people run e85 on dedicated tunes. So I don’t see why a flex fuel setup on pump e85 would be much worse. Except that it will always be on pump e85 instead of the occasional pure e85 fill.

I’m gonna run flex fuel on my car but I’m gonna be on MoTeC this is my fuel composition sensor

Detects ethanol content and adjusts tune accordingly

I've been looking for a flex fuel solution as well. ProEfi makes a plug and play stand alone that offers flex fuel, still trying to determine what will be lost transitioning to the stand alone

Good built in safety- I almost leaned out to blowing on e85 with my old beemer

I believe all Fords past 2011 are E85 safe due to standard E10 fuel, so all fuel system components can tolerate ethanol.
That said, the Proflex has been successful with new GT350s and should probably work with our cars.
I’m on a return system and custom E85 tune but this could be a good solution for guys that drive a lot where E85 isn’t as common.
Manny, where can I buy that sweet piece?
I just want to run a stand alone A-pillar gauge.

Hey J Shawn at fisher Motorsports made the custom sensor with the welded -6an fittings he’s the one doing my MoTeC system and my wastegate modification on my 4.7 KB if you need his contact info let me know he’s pretty easy to get ahold of though.
